Lailatul Qadar:

Laylat al-Qadr also known as the Night of Decree, or Night of Measures, is in Islamic belief the night when the first verses of the Quran were revealed to the Islamic prophet Muhammad (P.B.U.H). It is one of the odd nights of the last ten days of Ramadan. Muslims believe that on this night, God blesses everyone, forgives all sins, grants all prayers, and angels come down to earth.
